Setar is one of the Iranian plectrum-type string instruments, which is plucked by the player’s forefinger’s nail. Setar or Setouyeh is a three-cord instrument, which was converted into a four-cord instrument under the reign of the Qajars. It is, in general, an ancient and gnostic instrument usually played at the gathering of dervishes most often held at Khaneqahs (monasteries or houses of dervishes), which makes the listener feel high.
